How big is your room? W' x L' x H'

[bfalls]

Hello - I have visited this site for a while and have enjoyed the information that is exchanged, but I never joined to post until now. This is an interesting thread and I have discussed the room/system interaction to great length in the last several years with a couple of close friends - we have done several complete transformations in the exploration processs.

The first image shows my overall listening environment from about the listening position (there is another 10' behind the listening chair to an exterior wall). The dimensions are slightly distored due to a wide angle lens but the actual dimensions are the following: length 40', width 19' (at speaker placement), high cathedral ceiling where speakers are located.


The second image shows the rear of the room where the equipment is located which has a standard 9' ceiling.

The last shot is just a close up of the turntable in case someone was interested in what the heck it was...

Thanks for hosting a great site.

12' x 18' with a vaulted ceiling thats 8' high on the short wall that ascends to 12' over my listening position. the total space is actually larger because the left side opens to a hallway and theres a split level dining room directly behind me.

Purogave,
I m building a 17.75 x28 ft with vaulted ceiling , sidewall 7' 10" & peaking at 12.5 ft along the middle of the room. Am concern with the focussing effect of the slanting ceiling. So am wondering how you treat your vaulted ceiling

Bruce, welcome.
Very nice looking and I'm sure sounding room. Reminds me of a fellow a'phile friend who had a very similar room layout. The room was excellent sounding and I always enjoyed visiting. BTW, what is that TT, looks very nice.

Bruce -

Great first post! Absolutely beautiful room. Have to ask: where did you get the shelving system that holds the turntable...it's drop dead gorgeous!

 

[bfalls]

Thanks for the welcome. The turntable is a Technics Mk3 motor/platter/controller and I designed and machined the plinth (knowing I would use a Clearaudio arm/cartridge).

 

[bfalls]

Thanks for the compliment - I designed and built the stand to accomodate the equipment and power supplies while keeping my wife happy. This combination of rooms is my foyer, living room, dining room and so it is front and center in our house.

That is exactly what my friend's combination was as well. He actually placed the speakers into the the dining area and the TT along the long wall in the LR. Worked well.

Very nice clean design and machining Bruce, what's the plinth materials? All wood or aluminum and wood? And what is hiding in the rack behind the panels?

Thanks David - the plinth is a four piece design based on 6061 aluminum and brass (brass is the middle inset piece). The "panels" are actually drawers and they house the modified components and associated large format (automotive) Li-ion battery power supplies. Every component has been modified to be battery powered so the rack is not tethered to the wall except for a power supply used to charge the batteries. The components that are used are the Technics Mk3 power supply, a Mac Mini, a DAC/Pre combo unit, and modified class A monoblocks that are configured for complete balanced operation from cartridege to speaker.

well done. That plinth is exceptional amongst your other hidden details.

The plinth is gorgeous! Thanks for sharing. Did you modify your equipment to DC or are you using a DC/AC inverter? How many amp hours and how long before you have to charge the batteries? Reason I ask is that I'm looking at taking the system off the grid but I need a minimum of 76000wH which is a large bank of batteries and the wet ones need maintenance and dedicated housing. I can deal with that by my main problem is not knowing the qualities of different inverters as they effect the sound as much as dirty or clean AC.

Thanks Christian

Thanks David, All of the equipment has been converted to run on DC and the DC feeds are for the most part at the appropriate voltage for the circuits inside the components. In other words, there is no further regulation necessary (the Mac Mini still has internal regulation but that is the only piece).This is made possible by using a chemistry that has a flat discharge curve and using circuit voltages that are multiples of the individual cell voltages. The balancing of the cells becomes the issue - but this happens to be the business that I'm in so this is just a side project of sorts. Using an inverter is going to be a mixed bag as you have already discovered - most are not made for low noise as they are switching devices by nature. I would not have gone down this path with that mechanization. Because each component is configured for the voltage/capacity required there is not one number for how long I can operate without charging. The way I have it currently configured the class A amps will run about 7 hrs and the DAC/Pre and Mac Mini are not far behind. This is not a practical limitation for me as I don't have all day long listening sessions. I am using 3 x 14ah prismatic cells in parallel for the amps for example. Less for the other components. Are you sure you dont have an extra zero in your calculation? 76000wh is a about what a Tesla Model S has for capacity...

Yes, the inverters I heard one was nastier than the next, but I've seen similar installations in Japan without the noise of the inverter and glorious sound. I had the vendor do the calculations, I can't tell you if its wrong or not.

Purogave,
I m building a 17.75 x28 ft with vaulted ceiling , sidewall 7' 10" & peaking at 12.5 ft along the middle of the room. Am concern with the focussing effect of the slanting ceiling. So am wondering how you treat your vaulted ceiling

my primary speakers now are dipoles and I use no treatments. the dispersion in the vertical plane is minimal and the back wave cancels anything the wraps around the speaker. I experience much more direct sound than reflected as the ML's beam within a very narrow listening window. the patented "curvilinear" diaphragm imo, does little to negate this which is fine by me as I listen solo.

Hi Bruce (Bfalls) ..... Very nice setup and a great use of available space! I'm in So Cal and would love to have a listen if that might be possible? Excellent job!

 

[rbbert]

I'm going to try to post some new pictures. For some reason my photographic efforts are almost always sub-par...

Interestingly, one might think the front wall (with large window, equipment and CD racks) could use some other acoustic treatment (there are several TubeTraps and some decorative pillows, and some kind of "dots" on the window) but adding anything else or changing things has consistently degraded the sound.

Thanks Eddie - sure on the visit just send me an PM.

Awesome rbbert ! Have you thought about starting a CD retail outlet at all? Wow!
